A study hoping to prove that asparagus grown in Yorkshire is better for you than imported produce has been launched by a local food group.

The project is the brainchild of The Regional Food Group for Yorkshire and Humber, which is working with horticultural research body Stockbridge Technology Centre.

The study will compare the nutritional value of seasonal asparagus grown across Yorkshire with imported products.

"There is little research to justify claims about the advantages of regional produce and we wanted to have solid evidence to back this up," said food group research and development director Sarah Knapper.

"We believe the results will have an effect on sales and open retailers' doors for local producers."

The results of the research are due out in the summer.
